A second screen on top of the Switch 2? That would be adding additional weight for the screen and its bracket, add a wacky weight distribution and reduce battery life (power for the second screen). Also upscaled DS games would look very bad on those two big screens.
For DS & 3DS games they should use a "portrait mode grip" instead of a second screen. Similar to that:
The Switch 2 display is big enough in portrait mode to display the upper 3DS XL screen in almost full size (and that display area would be bigger than the "normal" 3DS upper display):
Just detach the Joy-Cons and attach the "portrait mode grip" with 3DS controls (similar weight as the two detached joy-cons).
You could display the upper screen of the 3DS (800x480) pixel perfect in the 1080x960 area of Switch2's upper screen half (should be "normal" 3DS size) or upscale the resolution from 400x240 to an 1080x648 area.
The lower 3DS display (320x240) could be displayed pixel perfect in an 640x480 area (same size as the pixel perfect upper screen) or in an 864x648 area (same size as the upscaled upper screen) or pixel perfect in an 960x640 area of Switch2's lower screen half:
DS games would be displayed in two pixel perfect 1024x768 areas (4x of the 256x192 DS-screens) or in two upscaled 1080x810 areas:
